Frequently Asked Questions - SRF-H2 SONY

How do I install the battery in the Sony SRF-H2?

While pressing the lid, slide it up to open the battery compartment. Insert one R03 (size AAA) battery with correct polarity. Close the lid by pressing it down until it clicks.

What should I do if the sound is weak or distorted?

Replace the battery. A weak battery can cause weak or distorted sound. The battery life is approximately 55 hours with Sony alkaline batteries for FM reception.

How do I switch between AM and FM on the SRF-H2?

Use the band selector located on the unit. Slide it to AM or FM as desired. Note: The SRF-H1 model does not have AM reception.

What is the SENS LOCAL/DX selector for?

Normally set it to DX for best reception. If a strong local station causes noise or multipath interference, set it to LOCAL for more stable reception with reduced noise.

Can I use the SRF-H2 while driving or cycling?

No. Avoid listening at high volume in situations where hearing must not be impaired, such as while driving or cycling, as outside sounds may become inaudible.

How should I clean the radio?

Clean the unit with a soft cloth dampened with a mild detergent solution. Never use abrasive cleansers or chemical solvents, as they may damage the unit.

What should I do if liquid or an object falls into the unit?

Remove the battery immediately and have the unit checked by qualified personnel before using it again.

Is the SRF-H2 safe to use in lightning?

If there is lightning while using the unit, immediately take off the headphone receiver to avoid risk of electric shock.

How do I adjust the headband for a comfortable fit?

Before putting on the receiver, pull out the support band fully from the headband. Adjust the headband to fit your head. When not in use, push the support band back under the headband.

What is the purpose of the light reflector?

The light reflector reflects car lights and other light sources at night, enhancing your safety when using the radio outdoors in low light conditions.

About the headphones

- Avoid listening with your headphones at so loud a volume that extended play might affect your hearing.

• At a high volume outside sounds may become inaudible. Avoid listening with your headphones in situations where hearing must not be impaired, for example, while driving or cycling.
• As your headphones are of open-air design, sounds go out through them. Remember not to disturb those close to you.

Warning

If there is lightning when you are using the unit, immediately take off the headphone receiver.

Radio operation

1 Set the POWER switch to ON.
2 For SRF-H2, set the band selector to AM or FM.
3 Turn up the VOL control to get sound.
4 Tune in the desired station with the TUNE control.

How to use the SENS LOCAL/DX selector

DX: Normally set it to this position.

LOCAL: Set it to this position, if a very strong station signal causes noise or if multipath* occurs. The reception will be more stable and noise will be reduced.

- Multipath, which often occurs in a street with big buildings or in a mountainous area, is reflection of signals that reach the receiver from structures or hills considerably later than direct signals. A multipath condition brings about high-frequency noise, distortion, and a poor stereo effect in FM reception.
